A View from the Road—December 2016

David Orr PE, Director, CLRP

Asphalt, concrete, brick, or gravel?

Today, these are the four materials used to surface a highway. There is one more material that has been used quite a bit: wood. You might have heard of plank roads in rural areas, but wood streets were common during the 1880's in American cities because they were quieter than cobbles and there was lots of wood available. However, the wood blocks used were prone to rutting and did not have good friction in the rain and snow (not to mention an odor on hot days when there were fumes from the horse waste that was absorbed into the wood). New York City, Washington, Detroit, Cleveland, and Chicago all had wood streets. Searching the internet, I found examples of such streets that still exist in Philadelphia, Chicago, and Cleveland.

Trying something new does not always work, but if you don't try you will never know. What innovations have you tried lately?
